struction is used it must be retained by a nut or cotter or othersimilar means, which become loose or lost, thus making it possible forthe link to become disengaged from either the car part orthe carrier.

My device is an improvement upon such structures and comprises means toretain one or both of the links in operativeposition, that is, to retainthe trunnions in their-proper bearings which means are actuated andretained in their normal position by gravity alone and which may beeasily moved 'out' of the normal position to permit the removal of theT-head from its hearing, which means ,are preferably permanentlyattached to a part of the car.

In the drawings:

Fig. 1 shows a plan View on the right half of the center line and on theleft hand of the center line a section on line 1-1 of Fig. 2'.

Fig. 2 shows a typical application of my device to a railway car.

Fig. 3 is a section on line 33 of Fig. 1.

Figs. 4 and 5 show fragmentary portions of the car part, link andretainer.

Fig. 6 is a perspective view of the retainer shown in Figs. 4 and 5.

Figs. 7 and 8 are fragmentary portions of the car part, link andmodified retainer.

Fig. 9 is a perspective view of the link shown in Figs. 7 and 8.

In the form illustrated the carrier 2 is swingably suspended from thestriking casting (or car part 3) by links 4 at its opposite ends, whichlinks are provided with T-heads or trunnions 5 at each opposite endwhich engage hearings in a carrier and car part, respectively. d

bearings while the coupler is in position upon If the journals for thetrun the I carrier. nions are made less than it is possible for thetrunnions to jump 'outof the bearings due to impacts of the cars inservice, particularly when being coupled, and if the vertical depthofthe bearing is made greater than the said 1 then the trunnions cannotbe removed from the bearings while the coupler is in operative positionon the carrier.

It is sometimes desirable to remove the carrier 2 or one of the links 4while the coupler is in position upon the carrier, therefore, it isnecessary to make the bearing (10) of at least one of the uppertrunnions of less vertical dimension than the permissible verticalmovement of the coupler (6), in which case some means must be providedto retain the trunnion in its bearing.

In my construction I provide such a means by retainer 11 having anelongated slot 12 therein which engages a pintle13 permanently securedto the striking casting or other part of the car. When in normalposition, which it assumes by gravity, the lower end of this retainer isadjacent the trunnion 5 so as toretain it in its bearing but with thepintle and slot arrangement it is capable of being moved in a verticaldirection to permit the removal of the link from its bearing. The pintle13 is provided with a head 16 and the lower portion of the retainerengages a recess 17 in the car part so that the head and the recessjointly and severally prevent the retainer from swinging in a planelaterally of the car. The retainer is of such width that it can notswing longitudinally of the car to an extent which would permit theremoval coupler shank, by the A. R. A., therebearing a tool is placedwithin the slot 20 under the retainer and the retainer is movedvertically out of the way.

Figs. 7, 8 and 9 show a modified construction wherein the pivot 30 ofthe retainer is sitioned normal to the constructon shown in Figs. 4, and6. The lip 31 on the retainer 32 prevents it from swinging out ofvertical line. 10 The accompanying drawings illustrate the referred formof the invention, though it is to be understood that the invention isnot limited to the exact details of construction shown and described, asit is obvious that various modifications thereof within the scope of theclaim will occur to persons skilled in the art.

I claim: The combination in a railway car of a car part, a carrierswingably suspended therefrom by links, one of said links having ajourml at its upper end engaging a bearing in the car part, a retainersecured to the car art so as to normally retain thejournal in itsbearing, said retainer having a slot therein engaging a pintle on thecar part whereby vertical movement of the retainer is permitted, andmeans to prevent the retainer from swinging in: any direction.
